However, how to use economical and practical equipment to achieve fast and efficient full inspection has always been a difficult problem faced by the industry. The main problem with vernier calipers is low precision and high skill requirements for inspectors; although micrometers have high precision, they have low detection efficiency and are not suitable for full inspection; three-coordinate detection is not only inefficient, but also expensive; special customized automated photoelectric equipment is used for detection. In addition to being extremely expensive, the equipment has poor versatility and a long production cycle. In addition, the equipment will be idle for a long time, and the economic efficiency is very poor. Therefore, there is an urgent need for a tool that can realize rapid detection of the outer diameter of circular and other shaped workpieces. Summary of the invention

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Embodiment 1:

[0026] A quick inspection tool for outer diameter inspection, its structure is shown in Figure 1 As shown, it includes a clamp body 1 with a U-shaped groove, a fixed detection head 2 fixedly arranged on one side wall of the U-shaped groove, and a go gauge block 3 and a stop gauge block 4 arranged on the other side of the U-shaped groove, wherein the stop gauge block 4 is located directly below the go gauge block 3, and the distance between the stop gauge block 4 and the fixed detection head 2 is adjustable.

[0027] In this embodiment, the fixed detection head 2 is fixed to the clamp body 1 by a screw structure. A side wall of the U-shaped groove of the clamp body 1 and the fixed detection head 2 are fixedly connected by a short locking screw 5.

[0028] In this embodiment, the following method is preferred for fixing the detection head 2: Figure 1 As shown, a first threaded hole is provided on one side wall of the U-shaped groove of the clamp body 1. The short locking screw 5 is fixed to the fixed detection head 2 by passing the short locking screw 5 through the first threaded hole and extending it into the first docking screw hole of the fixed detection head 2.

[0029] Please see again Figure 1 As shown, the installation method of the through gauge block 3 and the stop gauge block 4 in this embodiment is as follows: the other side wall surface of the U-shaped groove of the clamp body 1 is provided with a second threaded hole and a third threaded hole from top to bottom in sequence, and a long locking screw 6 and an adjustable screw 7 are respectively threadedly connected at the second threaded hole and the third threaded hole, and the ends of the long locking screw 6 and the adjustable screw 7 extend out of the second threaded hole and the third threaded hole respectively, and connect the through gauge block 3 and the stop gauge block 4, and the length of the adjustable screw 7 extending into the third threaded hole is adjustable. The stop gauge block 4 is rotationally connected to the adjustable screw 7. The third threaded hole and the adjustable screw 7 are respectively provided with a plurality of corresponding ones, and generally three to four parallel arrangements are selected. The length of the long locking screw 6 extending out of the second threaded hole is adjustable, and the long locking screw 6 is rotationally connected to the through gauge block 3.

[0030] The detection principle of this embodiment is as follows:

[0031] The whole device is connected by a screw structure to realize the quick installation of the block and the clamp body 1. The parallelism of the go gauge block 3 and the stop gauge block 4 and the required size of the go and stop gauges can be achieved by adjusting the adjustable screws 7 and the long locking screws 6. The fixed detection head 2 is connected by a short locking screw 5, and its main functions are wear resistance, good roughness, and easy replacement. The go gauge block 3 is at the top and is adjusted to the specified size by the long locking screw 6. The product 8 to be tested needs to pass the distance between the go gauge block 3 and the fixed detection head 2. If it fails, the product size is too large and unqualified. The stop gauge block 4 is at the bottom. After being adjusted to the specified size by the adjustable screw 7, the product 8 to be tested continues to move toward the stop gauge block 4 on the premise of passing the go gauge. If it stops at the stop gauge block 4, the product is qualified. Please refer to Figure 2 As shown in the figure, if the gap between the stop gauge block 4 and the fixed detection head 2 is entered, the product size is too small and unqualified. Therefore, the product only needs to be moved once to complete the go and no-go gauge detection. For products of different sizes and tolerances, it is only necessary to adjust the go gauge block 3 and the stop gauge block 4 to switch between different product detections. In particular, the detection of new products can be quickly switched and a large number of full inspection operations can be implemented.

[0032] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
